[heshsham basit]

Thanks a lot guys, all my issues are solved:

root at ubuntu:/home# mpiexec -f hosts.cfg -n 4 ./hello
Hello world from process 1 running on PC1 of 4
Hello world from process 3 running on PC1 of 4
Hello world from process 2 running on PC2 of 4
Hello world from process 0 running on PC2 of 4

:)
